POWER MECHANISM.

Application filed April 27, 1914, Serial No. 834,847.

To all whom t may concern Be it known that I, 112A H. WILLIAMS, asubject of the King of Great Britain, residing at Maple Creek, Provinceof Saskatchewan, Canada, have invented certain new and usefulImprovements in Power Mechanism, of which the following is aspecification.

This invention relates to power mechanism of the converting motion type,and the primary object of the invention is to organize a plurality ofgeared eccentric devices in such manner that the one will operate withrespect to the other by a movable wedging action to lift or shift alever or movable part in one direction and permit a return of the leveror movable part by gravitation of the eccentric devices in the oppositedirection, and thereby increase the power effectiveness of a primeoperating means which may be of any preferred forni.

A further object of the invention is to utilizeV a plurality of gearedeccentric devices, one of which at least is connected to a lever ormovable device, as an actuating means for the lever or movable deviceand operated through the medium of a pulling action relatively to one ofthe eccentric devices under the control of an eccentric element operatedby a prime power generating means to increase the effectiveness of ythelatter and also to convert rotary motion into reciprocating oroscillating motion.

`With these and other objects and advantages in view the inventionconsists in the construction and arrangement of the several parts whichwill be hereinafter more fully explained in one form to demonstrate thepracticability of the improved mechanical organization.

bearing uprights, supports or pillars 8. This power generating means maybe that disclosed by the application of Clarence B. Williams and lra H.W'illiams, filed May 28, 1918, Serial Number 770,555, or' any othersuitable power generating means. A shaft 9 is mounted in suitablebearing uprights 10 at a distance from the uprights or pillars 8,`

and thereon is secured a band wheel or pulley 11 in alinement with alarger band wheel' or pulley 12 on the power shaft 6, the pulleys 11 and12 being engaged by or having a band or belt 13 trained thereover fortransmitting the power from shaft 6 to shaft 7. As shown by Figs. 1 and2, a crescent-shaped' or otheranalogous eccentric 14 is `mounted on theshaft 9 and embodies a convex wiping edge 15 and a concave edge 16forming' secured and rises a suitable distance above.

the'said bar to receive the fulcrum 21 of an oscillating or verticallyreciprocating power lever 22 which may be of any suitable length andconstructed as shown by Fig. 3 with a longitudinal slot 23. The lever 22may engage or be attached to a pump rod 24- or any other mechanicaldevice that is adapted to be operated by the movement of the said lever22. 1n the bifurcation 19 of the bar 18 a spur gear 25 is eccentricallymounted by means of a bolt or pin 26 extending therethrough and theopposite portions of the bar 18, as shown by Fig. 1. The gear 25 may beadjusted to vary its eccentricity by forming the same with a pluralityof openings 27, and by shifting the gear into different positions thestroke and rapidity of movement of the same may be `readily changed. lnthe slot 28 of the power lever 22 a gear 28 is eccentrically mounted bymeans of a bolt or pin 29 passing through` the opposite side portions ofthe lever and the said gear 28, and the latter is also adjustable tovary its throw and rapidity of movement by forming the. same with aplurality of openings 30 which may be engaged tov by the pin or bolt 29in accordance with the adjustment of the gear 25. The gears 25 and 28are precisely alike in diameter and are similarly toothed, said gearsalways being held in mesh, and when the gears are in normal position theportion of the gear 25 at the greatest peripheral distance from thefulcrum or pin or bolt 26 engages the portion 'of the gear28peripherally nearest to the fulcrum pin or bolt 29 therefor, as clearlyshown by Fig. 1. The gear 28 has an arm 31 secured thereto at an angleand projecting-r to a point under the shaft 9 and carries africtionwheel or rotatable element 32 which is peripherally engaged by the edge15 of the eccentric 14.

The operation of the device as thus far described is very simple and isas follows; The shaft 9 is rotated by the power shaft 6 through themedium of the pulley 7, belt 13 and 'pulley 11 so aS to cause theeccentric 14 to rotate in the direction of the arrow shown thereon. Thewheel, roller or rotatable element 32 being always held in engagementwith the edge of the eccentric 14 and normally engaging the latter edgeat the point nearest the portion secured to the shaft 9 or penetrated bythe latter, the said wheel or rotatable element 32 will be presseddownwardly as the eccentric 14 rotates and the downward depression ofthe wheel or rotatable element 32 will correspondingly move the arm 31in the same direction and pull or rotate the gear 28 toward the shaft 9and eccentric 14, and this movement of the arm 31 and gear 28 willcontinue until the high end of the eccentric passes the upper centralportion of the wheel or rotatable element 32, wheny thelatter will moveinto the recess 17 and permit the arm 31 to rise, the elevation of thesaid arm and the wheel or rotatable element 32 being accomplishedthrough the gravitating movement of the gear 28 and its companion gear25. As the gear 28 is pulled over eccentrically on its fulcrum 29 itwill rotate the gear 25 and cause the latter to turn equally on itsfulcrum or the pin or bolt 26 and gradually bring the portions of theperipheries of the two gears 28 and 25 increasing in distance from theeccentric fulcrums of the said gears together and institute a wedgingaction which will operate to force the power lever 22 upwardly andcorrespondingly move the mechanical part that may be actuated thereby,as for instance the pump rod 24. This movement of the gears28 and 25will continue until the wheel or rotatable element 32 has passed intothe recess 17 of the eccentric 14, and the gears 28 and 25 are somounted and held in normal position relatively to each other that whenthe arm 31 and the wheel or rotatable element 32 are released from`downward depression or permitted to rise by coming into engagement withthe wall 16 of the recess 17, the said gears 28 and 25 willautomatically return to normal position for the reason that they are notcaused to overthrow their fulcrum points. The downward depression of thearm 31 and the wheel or rotatable element and the consequent operationof the gears 28 and 25 to elevate the power lever 22 and the successiverelease and automatic depression of the said power lever owing to theweight of the gears 28 and 25 will be rapidly ellected and willregularly ensue, and hence the power lever 22 will have a regularoscillation imparted thereto with increased power effectivenessrelatively to the prime power generating means, by reason of theeccentricity of the two gears 28 and 25 which always remain in mesh. Thepower lever 22, as above noted, may be very advantageously used inconnection with a pump rod or piston, or it may be a part of a pressuredevice oi' any other mechanism to which it is desired to apply or attachthe said lever.

'lhe structure shown by Figs. 5 and 6 is in all essentials similar tothat disclosed by Figs. 1 and 2, and similar reference characters areapplied to corresponding parts. In the organization as shown by Figs. 5and G, however, the arm 31 has its outer end bifurcated, as at 33, andtherein a gear 34 is eccentrically mounted thro-ugh the medium of a boltor pin 35, and instead of the eccentric 14, as shown by Figs. 1 and 2, agear 35 of the same dimensions as the gear 34 is eccentrically mountedon the shaft 9, the gears 34 and 3G being always retained in meshsimilarly to the gears 28 and 25. Primarily or when the gears 34 and 36are in normal position, the fulcrum pin or bolt 35 of the gear 34 is invertical alinement with and close to the shaft 9 directly under thelatter, and as the gear 3G is rotated the portions of the two gears and36 increasing gradually in peripheral distance, especially from the pinor bolt 35 and the shaft 9, will move together regularly and theincreasing distance as above referred to will effect a depression of thearm 31 and the gear 34 until the maximum peripheral distances of thegears 3land 36 relatively7 to the pin or bolt 35 and shaft 9 arereached, when the said arm 31 and gear 34 will be permitted to rise andthe gears 28 and 25 will return to normal position as shown, and at suchtime the power lever 22 will have been moved upwardly its maximumdistance and then depressed to the position shown by Fig. 5. The wedgingaction of the gears 28 and 25 in eccentric relation as hcreinbeforeexplained will be in all respects similar to that of like gears in theconstruction shown by Figs. 1 and 2, and as the arm 31 never passes theeccentric fulcrum point of the gear 28, the two gears 28 and 25 willgravitate or automatically swing around to normal position on the returnor rise movement of the arm 3l and the gear 34,-.

The improved power mechanism above eX- plained may be applied to variousmechanisms as stated, and it will be noted that not only is the primepower generating means effectively used with increased power, due to theeccentricity of the gears 28 and 25, but that rotary motion issimultaneously converted into oscillating or reciprocating motionthrough the actuation of the power lever It is proposed to modify thedimensions and general proportions of the parts of the improvedmechanism to adapt the same to various uses.
